Petunia plant named ‘Kerlatte’

ABSTRACT

A new and distinct cultivar of  Petunia  plant named ‘Kerlatte’, characterized by its mounding plant habit becoming more outwardly spreading with development; freely branching habit; moderately vigorous growth habit; early and freely flowering habit; medium-sized pale cream-colored flowers with dark purple-colored centers and venation; and good garden performance.

Botanical designation: Petunia×atkinsiana.

Cultivar denomination: ‘KERLATTE’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Petunia, botanically known as Petunia×atkinsiana and hereinafter referred to by the name ‘Kerlatte’.

The new Petunia plant is a product of a planned breeding program conducted by the Inventors in Cambridge, United Kingdom. The objective of the breeding program is to create new uniform Petunia plants with attractive flower coloration that have good garden performance.

The new Petunia plant originated from a cross-pollination made by the Inventors in August, 2011 in Cambridge, United Kingdom of a proprietary selection of Petunia×atkinsiana identified as code number 10-423-01, not patented, as the female, or seed, parent with a proprietary selection of Petunia×atkinsiana identified as code number 10-423-02, not patented, as the male, or pollen, parent. The new Petunia plant was discovered and selected by the Inventors as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Cambridge, United Kingdom in May, 2012.

Asexual reproduction of the new Petunia plant by terminal vegetative cuttings in a controlled greenhouse environment in Cambridge, United Kingdom since September, 2012 has shown that the unique features of this new Petunia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Petunia have not been observed under all possible combinations of environmental conditions and cultural practices. The new Petunia plant's phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Kerlatte’. These characteristics in combination distinguish ‘Kerlatte’ as a new and distinct Petunia plant:

-   -   1. Mounding plant habit becoming more outwardly spreading with         development.     -   2. Freely branching habit.     -   3. Moderately vigorous growth habit.     -   4. Early and freely flowering habit.     -   5. Medium-sized pale cream-colored flowers with dark         purple-colored centers and venation.     -   6. Good garden performance.

Plants of the new Petunia can be compared to plants of the female parent selection. Plants of the new Petunia differ from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Petunia are taller than plants of the         female parent selection.     -   2. Plants of the new Petunia are more mounding than and not as         trailing as plants of the female parent selection.     -   3. Plants of the new Petunia produce more cuttings per plant         than plants of the female parent selection.     -   4. Plants of the new Petunia are more rain-tolerant than plants         of the female parent selection.

Plants of the new Petunia can be compared to plants of the male parent selection. Plants of the new Petunia differ from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Petunia are taller than plants of the male         parent selection.     -   2. Plants of the new Petunia have smaller flowers than plants of         the male parent selection.     -   3. Plants of the new Petunia flower earlier than plants of the         male parent selection.     -   4. Flowers of plants of the new Petunia open fully whereas         flowers of plants of the male parent selection do not open         fully.

Plants of the new Petunia can be compared to plants of the Petunia ‘Viva Cappuccino’, not patented. In side-by-side comparisons conducted in Cambridge, United Kingdom, plants of the new Petunia differed from plants of ‘Viva Cappuccino’ in the following characteristics:

-   -   1. Plants of the new Petunia were more mounding than and not as         upright as plants of ‘Viva Cappuccino’.     -   2. Plants of the new Petunia had slightly smaller flowers than         plants of ‘Viva Cappuccino’.     -   3. Flowers of plants of the new Petunia opened fully whereas         flowers of plants of ‘Viva Cappuccino’ did not open fully.

Plants of the new Petunia can also be compared to plants of the Petunia×hybrida ‘Kerivoryvein’, disclosed in U.S. Plant Pat. No. 23,812. In side-by-side comparisons conducted in Cambridge, United Kingdom, plants of the new Petunia differed from plants of ‘Kerivoryvein’ in the following characteristics:

-   -   1. Plants of the new Petunia were larger than plants of         ‘Kerivoryvein’.     -   2. Plants of the new Petunia were more low temperature-tolerant         than plants of ‘Kerivoryvein’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown in 30-cm containers, with three plants each, during the summer in a glass-covered greenhouse in Cambridge, United Kingdom and under cultural practices typical of commercial Petunia production. During the production of the plants, day temperatures ranged from 18° C. to 28° C., night temperatures ranged from 14° C. to 20° C. and light levels averaged 50 kilolux. Plants were pinched one time and were ten weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
